Copy file src to dst. The files can be specified as
pathnames or FSSpec objects. If createpath is non-zero
dst must be a pathname and the folders leading to the
destination are created if necessary. The method copies data and
resource fork and some finder information (creator, type, flags) and
optionally the creation, modification and backup times (default is to
copy them). Custom icons, comments and icon position are not copied.

If the source is an alias the original to which the alias points is
copied, not the aliasfile.

Tell the finder that some bits of finder-information such as creator
or type for file dst has changed. The file can be specified by
pathname or fsspec. This call should prod the finder into redrawing the
files icon.
